The below mentioned article provides a short note on the aminoacylation of tRNA. Role of Transfer RNA: Transfer RNA molecules play a key role in the process by delivering amino acids to the ribosome in an order specified by the mRNA sequence; this ensures that the amino acids are joined together in the correct order. Cells usually contain many species [...]
The following points highlight the three main stages for translation of RNA and protein synthesis. The stages are: 1. Initiation of Polypeptide 2. Elongation of Polypeptide: 3. Termination of Polypeptide. Translation of RNA: Stage # 1. Initiation of Polypeptide: Ribosomes exist as separate large and small subunits. The first step in translation involves the binding of the small ribosomal subunit [...]
The following points highlight the five main classes of chemical compounds in chromatin. The classes are: 1. Nucleic acids 2. Basic proteins or histones (protamines in sperm nuclei of some fishes and birds) 3. Acidic proteins (Non-Histones) 4. Lipoproteins 5. Associated inorganic molecules. Chemical Compounds in Chromatin: Class # 1. Nucleic Acids: The nucleic acids are of two types: (i) [...]
